"For years notebook users looking for desktop like performance were forced to purchase notebooks that used desktop components like processors and hard drives. The notebook main board and processor have evolved into components that rival their desktop counterparts, but the 2.5" platter based notebook hard drive has taken more time to reach the same speeds when compared to their desktop equivalent.
When Western Digital announced their new Scorpio Black 750GB and the marketing department advertised it as a notebook drive with desktop performance, I quickly took note. Last year we looked at the Scorpio Blue 750GB, the 5,400 RPM version of the Scorpio Black and came away impressed with the capacity offered, but the speed was only on par with many other 5,400 RPM drives."
